Micr olepidop tera 

By J. D. Bradley 
Commonwealth Institute of Entomology 

The collection of Microlepidoptera formed by Mr. D. S. Fletcher during the Ruwenzori 
Expedition 1952-3 is among the most important of this group known from the highlands of 
East Africa. The special attention paid by the Expedition to the upper limits of the montane 
rain forest zone and the ericaceous and alpine belts lying between 8,500 ft. and 14,000 ft., where 
hitherto little collecting of Microlepidoptera appears to have been done, has yielded much new 
information concerning the composition and affinities of the microlepidopterous fauna of the 
Ruwenzori Range. Many of the species taken at these higher altitudes have proved to be either 
new to science or species previously known oidy from type material. The fauna of the regions 
below the level of the montane forest zone, which begins at about 5,000 ft., is more typically 
African in character and includes species with a wider distribution. 

The total number of specimens collected by Mr. Fletcher belonging to the families generally 
classed as Microlepidoptera, excluding Pyraloidea, exceeds 1,200. A little over half of these, 
mainly specimens from the higher altitudes, have now been studied and the results are presented 
in this paper. Such material from the lower levels as has so far been studied is included: the 
remainder still awaits study. 

The material examined has also included some from other sources, notably from the collections 
made by F. W. Edwards and D. R. Buxton during the British Museum Expedition to East 
Africa in 1934-5, an d by the G. F. de Witte Expedition to the Congo in 1947. For the privilege 
of examining the Microlepidoptera collected by the de Witte Expedition I am indebted to Dr. 
A. Houben, Director of the Institut des Pares Nationaux, Brussels, and his predecessor the late 
Dr. V. van Straelen. Only the very small part of this extensive collection from the Congo which 
supplements the Ruwenzori collection is studied in this paper. 

The material discussed in the present report includes ninety species, forty-eight of them new 
to science, and a new subspecies. No new genera are erected, species being placed in existing 
genera, though in a number of cases, it is evident that the assignment is taxonomically not 
strictly tenable. Where such provisional generic combinations occur I have commented on them 
in the text. This course has been adopted because extensive generic revision is required in prac- 
tically every family mentioned herein, and it is considered inappropriate to attempt such revision 
in the present study. 

The types of new species described are in the British Museum (Natural History) unless indicated 
otherwise. Colour terms used in the descriptions are based on Ridgway (1912) and KLornerup 
& Wanscher (1963).

A detailed list of collecting localities and the itinerary of the Expedition appears in an earlier 
part under the series title (Evans & Fletcher, 1958). The geographical distribution of previously 
described species recorded below is given so far as known. 

The illustrations of the wings (Figs. 1-62) are reproduced from photographs taken by Mr. P. 
Green, a staff photographer of the British Museum (Natural History). As the individual illustra- 
tions are considerably enlarged and of varying magnifications, the wing expanse (from wing tip 
to wing tip) of each species has been given, in parentheses, after the caption. The photomicro- 
graphs of the genitalia (Figs. 63-215) were taken by Mr. J. V. Brown, also of the museum 
photographic section, and I am indebted both to him and his colleague for these valuable visual 
aids to identification. 

The study of Mr. Fletcher's Ruwenzori material began some years ago, while I was on the 
staff of the British Museum (Natural History), and has continued intermittently. It gives me 
pleasure to acknowledge the encouragement that I received initially from Mr. N. D. Riley, c.b.e., 
then Keeper of Entomology, and subsequently from his successors Dr. W. E. China, c.b.e. and 
Mr. J. P. Doncaster ; and also from Mr. W. H. T. Tarns, to whom I am additionally indebted 
for reading and criticising the original manuscript. I am also greatly obliged to Dr. A. Diakonoff, 
of the Rijksmuseum van Natuurlijke Historie, Leiden, for his opinion regarding the generic 
affinities of certain of the Tortricidae.

The two Ruwenzori specimens show evidence of variation within this species, previously 
known only from the unique type male from the Congo. Unlike the type they exhibit little trace 
of reddish brown suffusion in the coloration of the fore wing, and the wing markings are a 
comparatively blackish brown; in addition the semioval whitish patch on the costa is suffused 
with greyish and streaked with fine blackish lines. A prominent feature is the broad sinuous 
whitish band, suffused with greyish, extending from near the base of the fore wing to the middle 
of the inner margin (dorsum), curving apicad and finally merging with the distal margin of the 
semioval costal patch; in the type this band is almost completely obliterated by a brownish 
suffusion except for a short whitish furcation emitted from the costal patch. 

The genitalia of the Ruwenzori specimens have been compared with those of the type and 
found to be identical except for slight differences in the cornuti of the aedeagus. In the type all 



Microlepidoptera 83 

three cornuti - one very small thorn-like cornutus and two long slender cornuti - are straight, 
while in the Ruwenzori specimens the two larger cornuti are strongly curved. This difference at 
the most probably indicates no more than subspeciation. 
Distribution: Congo. 

Trachybyrsis euglypta Meyrick 

Trachybyrsis euglypta Meyrick, 1927, Exot. Microlepidopt.. 3 : 368. 

ruwenzori: Mahoma River, 6,700 ft. (Fletcher), 1 Nyinabitaba, 8,650 ft. (Fletcher), 1 
Nyamaleju, 10,530 ft. (Fletcher), 1 Bigo, 11,400 ft. (Fletcher), 1 q\ 

This species has hitherto been known only from the type, a female erroneously described by 
Meyrick as a male. The four Ruwenzori specimens, collected at various altitudes between 6,000 
ft. and 12,000 ft., show that the species has a vertical distribution which includes rain forest and 
the ericaceous and alpine belts. Of interest is that the wing expanse of the moths increases with the 
altitude of the localities. The Mahoma River specimen, taken at 6,700 ft., is the smallest, with a 
wing span of 24 mm.; the Nyinabitaba specimen, 8,650 ft., has a wing span of 30 mm., which 
is similar to that of the type from Niansa, 5-6,500 ft.; the Nyamaleju specimen, 10,530 ft., 
measures 32 mm.; and the Bigo specimen, 11,400 ft., is the largest and measures 35 mm. 

The Ruwenzori specimens differ superficially from the type in having the fore wing distinctly 
more greenish in colour. 

Distribution: Rwanda. 

Trachybyrsis hypsitropha sp.n. (Figures 1, 63) 

o* 37 mm. Labial palpus warm buff, darkened with fuscous irroration anteriorly. Head warm 
buff mixed with dark ochraceous-buff especially on crown. Thorax and tegula ochraccous-buff 
mixed with ochraceous-tawny, sometimes suffused greyish. Antenna with scape dark ochraceous- 
buff above, whitish below; flagellum warm buff, underside suffused with greyish and with basal 
segments marked with fuscous. Fore wing ground coloration light buff or light ochraceous-buff, 
almost entirely overlaid with fuscous suffusion liberally sprinkled with blackish, the whole 
sparsely irrorate with isabclla color, giving a partially greenish tinge to the wing; markings 
diffuse and ill-defined, antemedial fascia narrow, dilated at costa, hardly discernible but usually 
distinguished by slightly heavier fuscous suffusion; terminal fascia narrowly edged inwardly 
from costa to near tornus with pale buff ground colour, diffuse distally, containing 3 or 4 quadrate 
hair brown strigulae along costa interspersed with ground colour; cilia pale buff intermixed 
with a sprinkling of blackish. Hind wing light buff, obscurely mottled with narrow, sinuous, 
greyish lines ; cilia light buff, with a fuscous-black sub-basal line. 

Male genitalia (Fig. 63). Very similar to T. euglypta Meyrick but differing as follows: Transtilla 
with medial arm very short, well sclerotized and strongly denticulate at apex; aedeagus slightly 
longer than in euglypta but with apex not so strongly curved ventrad, containing two thorn-like 
cornuti as in euglypta. 

ruwenzori: Kimemba Camp, 11,900 ft., i.viii.1952 (Fletcher), J, holotype, genitalia slide 
3606; Lamia Valley, 11,900 ft., 30-31. vii. 1952 (Fletcher), 2 

The structure of the male genitalia of this species is very similar to that of euglypta, as mentioned 
above, and both species are superficially similar in general facies and are evidently closely related.

In hypsitropha the coloration is more sombre and the fore wing markings more obscure than in 
euglypta. Both species are remarkable for their huge size, and probably have the greatest wing 
expanse of the known species of this family. The only other member of the genus, T. chionochlaena 
Meyrick, which occurs in Abyssinia, is quite dissimilar superficially and in structure of male 
genitalia, and is considered as doubtfully congeneric.

Previously known only from the type, a male collected in the Congo at 4,000 ft. The Ruwenzori 
specimens resemble the type in coloration and markings but are considerably larger, the male 
having a wing expanse of 20-22 mm., the female 24-25 mm., while the type measures 18 mm. 

The male genitalia and wing venation indicate generic affinities with Paramesiodes Diakonoff. 

Distribution: Congo. 

Capua spilonoma gitona subsp.n. (Figures 2, 64-66) 

Capua spilonoma Meyrick, 1932, Trans. R. ent. Soc. Lond., 87: 507. 

16-18 mm. General coloration of fore wing darker and more brownish-tawny than in nominate 
subspecies from Abyssinia, and wing expanse slightly less. Minor differences are evident in the 
male genitalia (Figs. 64-66) ; in gitona the keel-like projection a little distad of the middle of the 
sacculus is produced to a sharp thorn-like point, and in some examples the ventral edge of the 
sacculus tends to be irregularly serrulate; the lateral lobe (labis) of the transtilla is evenly rounded 
compared with the almost pyramidal outline in spilonoma. The solitary, prominent, acuminate 
lateral tooth on the apical section of the aedeagus in spilonoma is replaced in gitona by a low 
weakly serrulate ridge.

but with the outer (distal) margin of the basal patch or fascia almost straight and not convex and 
reaching to middle of inner margin (dorsum) as in eustropha. The ground colour of the fore wing 
is warm buff, extensively suffused with buffy brown mixed -with a trace of vinaceous drab - in 
eustropha the fore wing is extensively suffused with vinaceous drab, especially in the areas of the 
wring between the markings, and is very distinctive. Hind wing pale warm buff, diffuse greyish 
maculae distallv and around margins ; cilia light buff, suffused greyish apically.

variable: in male holotype and majority of paratypes as follows: ground colour greyish light buff, 
areas between markings lightly irrorate with brownish; markings brownish with a variable 
admixture of tawny, mostly diffuse and ill-defined ; basal marking broad, outer margin verv diffuse, 
strongly outward-convex at middle ; medial fascia stronger, outward-oblique, somewhat undulate, 
inner margin well-defined with coloration often darker and sometimes with an admixture of tawny 
and blackish producing a coffee coloured effect, outer margin mostly obliterate, traceable 
from costa, where fascia is very narrow, to end of cell area, strongly outward-oblique ; apical area 
of wing from about J on costa to termen a little above tornus suffused with greyish, slightly darker 
on costa, an indication of a broad pre-apical costal blotch, inner margin of apical area sometimes 
strengthened with a few specks of tawny or dark brown ; in female allotype and two female para- 
types the coloration is much darker and the general appearance of the fore wing is greyish fuscous 
with markings dark brown; in other specimens the markings are weak or obliterate; cilia con- 
colorous. Hind wing whitish or ochreous-white, sometimes with greyish suffusion, distal half 
weakly mottled with dark grey, most strongly towards apex; cilia concolorous.

Larger than the two Malagasy species, P. longirostris Diakonoff and P. minor Diakonoff, the only 
other species previously known representing the genus. In those two species the uncus of the male 
genitalia is broad throughout its length and truncate distally, appearing rectangular in shape 
viewed ventrally; in aprepta the uncus is narrower basally and dilated and rounded distally. 

Niphothixa agelasta sp.n. (Figures 6, 76) 

o* 1 8 mm. Labial palpus fuscous exteriorly, whitish interiorly ; tips of scales on exterior lightened 
with pale drab-grey producing an irrorate effect, apex of terminal segment pale drab-grey. Head, 
thorax, tegula, patagia and antenna greyish fuscous, scales tipped with drab producing an 
irrorate effect. Fore wing ground colour warm buff, diffusely irrorate with greyish fuscous striae 
forming transverse chains especially in distal area; markings fuscous mixed with fuscous-black, 
basal patch diffuse, strongest at costa, outer margin obtusely outward-angulate before middle, 
weakly outlined with fuscous-black ; medial fascia outward-oblique from costa before middle to 
inner margin (dorsum) near tornus, containing a weak admixture of ochreous in central and

a few ochreous scales in striae between apex of preapical marking and tornus; cilia warm buff, a 
thin submedial drab-grey line along termen broadly edged with strong fuscous suffusion, a 
fuscous streak from inner margin before tornal angle. Hind wing drab, wbitisb along costal 
margin; cilia warm buff, a fuscous sub-basal line. 
Male genitalia (Fig. 76).

The genus Niphothixa Diakonoff was originally erected to accommodate two species from 
Madagascar. Of these, the species described above, N. agelasta, and also the following new species, 
are nearest N. niphadacra Diakonoff, having veins 3 and 4 of the hind wing connate. N. agelasta 
differs superficially from niphadacra in having the thorax a more or less uniform greyish fuscous, 
the apical fourth not being yellowish-white, and in the general coloration of the fore wing, 
which in niphadacra is a "deep fulvous-purple". 

Niphothixa ophina sp.n. (Figures 7, 77-78) 

o* 18-20 mm. Labial palpus basal and second segments snuff brown diffusedly irrorate with bister 
exteriorly, roughened dorsal scales suffused cinnamon-buff interiorly; terminal segment sayal 
brown diffusedly irrorate with bister. Head, thorax and tegula bister, a weak cinnamon-buff 
suffusion medially from crown of head to middle of thorax. Antenna fuscous, latero-posterior 
scaling bister basally becoming warm buff towards apex; scape light buff, overlaid with mummy 
brown above. Fore wing ground colour cinnamon, with extensive light vinaceous-drab suffusion; 
markings bister mixed with mummy brown ; basal marking occupying J, outer margin slightly 
outward-concave ; medial tascia from costa before middle, outward-oblique to inner margin 
(dorsum) before tornus, narrow and well-defined at costa, broadening and becoming obliterate 
beyond middle ; preapical triangular costal marking strong, emitting a diffuse bister streak from 
apex to termen parallel with medial fascia, a few scattered mummy brown striae distad and basad 
of this streak, a few thick short striae on inner margin between basal patch and medial fascia and 
along costa; radial veins finely etched with mummy brown penetrating into cilia as thickened 
dashes at tornus; an admixture of russet scales, not very conspicuous, along termen; cilia warm 
buff, a broad mummy brown medial band from apex to tornus, inner edge sharply denned, 
outer margin diffuse and extending into cilia. Hind wing pale warm buff, weakly infuscate in 
distal and vannal areas, some scattered stronger fuscous mottling at apex and along terminal 
margin; cilia concolorous, a broad wen-defined greyish brown sub-basal line, apices often whitish. 
At the base of the abdomen and most clearly visible in dissected specimens is a pair of subventral 
patches of specialised scales (Fig. 78). 

Male genitalia (Fig. 77). Sacculus broad, compressed, without tooth-like projection. Aedeagus 
long, curved throughout its length, 4 or 5 comparatively short blade-like cornuti.

Distinguished from the previous species by the dark coloration of the fore wing and the weaker 
contrast between the transverse fasciae and the ground coloration.

The male of this species is remarkable for the peculiar bifurcate aedeagus of the genitalia. This 
and certain other characters found in the male genitalia indicate that the species does not properly 
belong in the genus Tortrix L. (sensu stricto). 

Distribution: Nyasaland (bred from spun shoots of cotton, Gossypium). Kenya (bred from 
Arabian coffee, Coffea arabica), Ghana, Sierra Leone and Principe I. 

Tortrix edwardsi sp.n. (Figures 8, 79) 

cT 20 mm. Labial palpus warm buff, basal and second segments with a weak admixture of ochra- 
ceous-tawny exteriorly, terminal segment wholly suffused greyish. Head ochraceous-buft mixed 
with ochraceous-tawny. Thorax and tegula ochraceous-tawny, thorax strongly suffused hair 
brown, apical half of tegula suffused drab-grey. Antenna warm buff, scape suffused greyish above. 
Fore wing ochraceous-buff diffusedly marked with hair brown striae especially along costa, a 
moderately strong fuscous mixed with ferruginous fascia from costa before middle, narrow and 
moderately well-defined at costa, quickly broadening and forking to straddle a well-defined 
triangular cream colour marking, the base of which rests on inner margin (dorsum) from about 
j to a little beyond middle and with apex reaching to about middle of wing, distal furcation of 
fascia very broad and somewhat diffuse, outer edge slightly sinuate extending obliquely to dorsum 
near tornus, proximal furcation broadening gradually towards inner margin; triangular marking 
traversed vertically by several short striae similar in coloration to fascia; a poorly defined sub- 
triangular preapical marking resembling fascia, blended with a diffuse terminal fascia the inner 
margin of which is moderately well-defined and extends from apex of costal marking to termen 
near tornus and is parallel with outer edge of medial fascia; cilia (worn in type) concolorous. 
Hind wing cinereous; cilia cartridge buff, with a greyish sub-basal line. 

Male genitalia (Fig. 79). Uncus digitate, apex bluntly rounded, setose ventrally. Socius pendu- 
lous, hirsute. Gnathus a pair of compressed sclerotized arms with apices fused medially. Sacculus 
narrow, apex aciculate, a strong inward-projecting slender tooth-like projection near base, three 
slightly smaller tooth-like projections spaced equidistantly along inner edge of ventral margin. 
Transtilla labides globulose, bristling with strong denticulations, caudal margins connected 
medially by a short sclerotized rod-like bar. Aedeagus stout, orifice dorsal, apex bifurcate, upper 
prong produced to a long aciculate point, lower prong in the form of a strong tooth-like pro- 
jection opposite orifice, curved slightly ventrad. 

ruwenzori: Namwamba Valley, 6,500 ft., xii. 1934-1.1935 (Edwards), 1 <3\ holotype, 
genitalia slide 7195. 

Belonging to a species group which includes Tortrix meridionana (Walker), sp.rev., T. adustcma 
(Walsingham), sp.rev., and T. dorsiplagana (Walsingham), sp.rev., and superficially nearest 
the last species. These species are variable and may sometimes bear a close superficial resemblance 
to each other, so that edwardsi is more reliably distinguished by the strongly bifurcate apex of 
the aedeagus in the male. 

The three species mentioned above as allied to edwardsi are removed from synonymy, together 
with T. reciprocana (Walker), sp.rev., and T. capitana (Felder), sp.rev., under T. capensana 
(Walker), where they were placed by Meyrick (1908, Proc. zool. Soc. Lond., 1908 : 723). The 
re-examination of the types of capensana, meridionana, capitana and reciprocana, which are in the 
British Museum, has shown them to be distinct specifically; and examination of specimens of 
adnstana and dorsiplagana from Walsingham's collection (the types of the last two species not 



Microlepidoptera 89 

being available as they arc in the Museum at Cape Town) indicates that these arc also distinct 
species. 

Contrary to Meyrick's opinion (loc. cit), none of the above species is a true Tortri.x. T. capensana 
is generically distinct from the other species hitherto placed in synonymy with it and belongs in a 
genus near Capua. The other species, including cdwardsi, properly belong in a genus related to 
Ptycholonia Stephens and Leontochroma Walsmgham, but as they cannot be more accurately 
placed they are for the present retained in the genus Tortri.x.

Nyamaleju, 10,530 ft. (Fletcher), 2 $\ Bigo, 11,400 ft. (Fletcher), 1 $. 

The additional Ruwenzori material shows chalicodes to be a true montane species, occurring 
at altitudes from a little under 6,000 ft. to over 1 1,000 it. At higher elevations the wing expanse 
increases considerably and the fore wing markings become obsolescent, the wings then being 
almost unicolorous. On average the female is larger than the male, the wing measurements for 
the Ruwenzori specimens being: q* 20-32 mm., $ 28-33 mm. 

This species does not belong in the genus Tortri.x, its generic affmites lying nearer Parapaudemis, 
but there appears at present to be no described genus to which it can be properly transferred. 

Distribution: Kenya. 

Tortrix stenophora sp.n. (Figures 9, 80-85) 

S $ 10-15 mm. Labial palpus ochraceous-buff, paler interiorly, second segment slightly infuscate 
exteriorly. Head, tegula and thorax ochraceous-buff, tegula lightly and thorax heavily suffused 
with drab. Antenna light buff, apices of segments spotted with blackish brown dorsaily; scape 
ochraceous-buff, infuscate dorsaily. Fore wing of male with moderate costal fold from base to 
near middle, ground colour in both sexes light buff diffusely irrorate with brownish and drab 
mixture, a few poorly defined scattered greyish strigulae and striae, darker along costa; markings 
yellowish light brown, suffused greyish; basal patch indicated by slight costal and dorsal suffusion; 
medial fascia outward-oblique from before middle of costa to dorsum near tornus, moderate, 
inner margin straight or slightly undulate, distal margin diffuse and dilated with drab suffusion 
in tornal proximity; preapical costal patch suffused greyish, produced inwardly as a rather narrow 
fascia extending obliquely towards termen, well defined along inner margin which is slightly 
undulate and edged with ochreous mixed with blackish and extends to tornus, diffuse and obscure 
distally and reaching termen before middle; cilia light buff or ochreous, a greyish sub-basal line.

Closely related and superficially very similar to Tortrix scaeodoxa Meyrick. The male genitalia 
of both species are structurally similar but differ in the shape of the valva which is ovate 111

scaeodoxa and triangulate in stenophora, and in the uncus which in scaeodoxa is more elongate and 
produced distally to an acute point. Neither species strictly belongs in the genus Tortrix, and j 
the structure of the male genitalia indicates their generic affinities lie near Adoxophyes, but the 
separation of veins 7 and 8 in the fore wing, which in Adoxopliyes are stalked, excludes them from 1 
that genus. They are therefore provisionally retained in Tortrix, since no described genus can be I 
found which will properly accommodate them.

ruwenzori: Ibanda, 4,700 ft. (Fletcher), 3 q\ 

The above synonymy has been established following the comparison of type material of 
M. hedrastis (Meyrick) and M. prona (Meyrick), and topotypical specimens of M. elegans deter- 
mined by Walsingham. All three species were described from South Africa. The type of elegans \ 
is in the South African Museum at Cape Town, and has not been examined during the present 
study. The type of prona is in the British Museum (lectotype designated by Clarke, 1958, Catalogue 
of the Type Specimens of Microlepidoptera in the British Museum (Natural History) described 
by Edward Meyrick, 3 : 252, pi. 126, figs. i-ib). 

Cacoecia hedrastis Meyrick was synonymised under Tortrix elegans by Meyrick (1912, Lep. Cat., 
10 : 33), but neither a type nor subsequent lectotype designation appears as yet to have been 
made for this species. A male in the Meyrick collection in the British Museum, representing one I 
of the two original syntypes, is therefore now selected as LECTOTYPE. It bears labels with the i 
following data, "Pretoria, Transvaal, Janse 3.06" "E. Meyrick coll." "Genitalia slide No. 8054". 

Distribution: M. elegans occurs in S. and E. Africa; examples are known from Natal, Pretoria, | 
Transvaal, Mashonaland, Kenya, Uganda and the Congo.

warm buff above, marked with mummy brown dorsally except at apex. Thorax and tegula olive 
brown with ochreous admixture, tegula slightly paler towards apex. Fore wing with strong 
costal fold to near middle; ground colour light drab, a few dispersed olive brown dots or striae 
edged and mixed with raw sienna; markings basically olive brown, as follows: a moderate 
diffuse basal patch mixed with olive brown extending into costal fold; medial fascia well defined, 
narrow at middle of costa quickly dilating and resting on inner margin (dorsum) from about f

to tornus, almost completely suffused with vinaceous-grey mixed with ochrcous except at 
margins, inner (proximal) margin straight, slightly outward-oblique from costa, outer (distal) 
margin curved outwards from below costa, continuing in a bold curve to tornus, a nearly 
constant admixture of raw sienna distributed along both margins and forming a weak yellowish 
demarcation line; a similar but somewhat broken and indefinite pre-apical marking on costa, 
followed by an obliquely transverse chain of dark olive-brown striae from near apex of marking 
to termen above tornus, similar scattered striae in terminal area beyond, surrounded by vinaceous- 
grey suffusion overlaying almost entire terminal area; cilia ochraceous-buff, a distinct broad 
vinaceous-grey sub-basal line, broadening and becoming diffuse around tornus. Hind wine; drab, 
whitish along costa towards base; cilia light buff, with a strong, drab sub-basal line. 

Male genitalia (Fig. 86). The caudal margin of VHIth sternite bears an array of eight very 
large, curved, prong-like setae, arranged four at each side. In the specimen shown in Fig. 86, 
three of the left-hand group of setae are missing.

The structure of the male genitalia of this species indicates close relationship with Metatnesia 
endopyrrha (Meynck), comb.n., in which the Vllftb sternite is similarly developed and bears a 
similar number of prong-like setae. The two species differ superficially in coloration of the hind 
wing, octogona lacking the orange coloration present in endopyrrha.

follows: denticulate cluster on dilated lateral portion of transtilla with teeth longer and base 
shallower; aedeagus similarly tapered towards apex but with rim of tapered portion smooth 
and not minutely denticulate as in panochra, a dense internal sheaf of hair-like cornuti.

This species may tentatively be placed next to E. atycta. The separation of the gnathus arms, 
which are free and not fused medially as in the male genitalia of atycta and other related species, 
is atypical of the genus.

The only other known species belonging to this genus is C. perspicua Meyrick, described from 
a unique female collected on Kilimanjaro. The type has not been available for examination 
during the present study; from the description it resembles fietcheri in size and general appearance 
but differs in the pattern of the black markings of the fore wing, notably in the more numerous 
markings on the costa which has about eighteen transverse marks or small dots. 

Endothenia alpigena sp.n. (Figures 17-19, 98-102)

extensive fascia from costa at §, constricted at middle thence divided, one fork reaching termen 
immediately above tornus, the other fork going to inner margin (dorsum) a little before tornus, 
in some examples (Fig. 19) these fasciae are partially or entirely obliterated by fuscous suffusion;

is bordered costally with a few additional ferruginous-orange scales; costa irregularly marked 
with fuscous-black strigulae; small white interneural or neural dots spaced along termen which 
may sometimes have a heavier concentration of ferruginous-orange ; cilia fuscous, a strong fuscous- 
black basal band from apex to tornus inclusive, cilia along termen tipped with yellowish-white 
or greyish yellow. Hind wing white, apical area dark fuscous, in some examples the normally 
clear white area of the wing may be suffused with greyish; cilia white, a broad dark fuscous 
sub-basal line from above apex to below middle of termen; cilia along this line suffused with

The longitudinal markings of the fore wing, well-defined in the male and obsolescent in the 
female, and the reduced development of the fore wing in the female, make orestera a species of 
distinctive and unusual appearance. It is similar in size to O. phyllodoxa (Meyrick) with which it is 
provisionally associated until such time as it can be more precisely placed generically. Apart from 
similarity in size, the two species are quite distinctive and readily separated by difference in general 
coloration of the fore wing, orestera lacking the greenish coloration prevalent in phyllodoxa.

UGANDA Bundibugyo, 3,440 ft. (Fletcher), 7 £ $; Semliki Forest, 2,850 ft. (Fletcher), 5 S $• 

The above new synonymy has been established following an examination of type material in 
the British Museum. 

The type female of claricoma from Uganda is identical with the Ruwenzori specimens in 
coloration, and with them differs from the type female of bathrota from Transvaal, which has 
much lighter coloration. The abdomen of claricoma is missing but the genitalia of the type of 
bathrota (slide J.F.G.C. 4529) have been compared with the Ruwenzori specimens. 

The difference in coloration may indicate that the E. African material belongs to a distinct 
subspecies, for which the name claricoma could be used, but more material from the Transvaal is 
needed for study in order to establish this. 

Distribution: Transvaal and Uganda.

and tegula light buff diffusedly irrorate with fuscous, fuscous irroration variable, in some examples 
dense and heavy especially on head. Antemia fuscous, in male finely ciliate, roughened in both 
sexes but more so in male, with raised scale-tippets at apices of segments. Fore wing light buff 
diffusedly irrorate with fuscous, more heavily in some examples than others; costal margin 
narrowly fuscous, containing five chalybeous dots, the first sometimes elongated, spaced along 
apical half of costa from middle to apex; thick silvery lines finely edged with dark fuscous 
arise from certain of these dots : from first dot near middle of costa extending transversely about 
^ across wing, from fourth dot extending, outward-curved, to termen near tornus, interrupted 
near middle of wing in some examples, from fifth dot (apical) extending along termen to middle, 
sometimes fusing with interrupted apical portion of line from fourth dot or with distal part of 
same line; in latter examples whole of termen appears edged with silver; short silvery blobs 
edged proximally with dark fuscous arise from second and third dots; a silvery line similar to 
those emitted by costal dots arises from middle of dorsum, curving gently distad to terminate 
beyond middle of wing near third costal dot; directly distad of this line is a narrow light yellow 
(butter yellow) fascia reaching across wing to costal margin, enclosing first and second chalybeous

brown. Hind wing greyish silver ; cilia greyish brown. 



Micwlepidoptera IO y 

This is a variable species and the above description is of the commonest form among the 
material available and is considered typical. A form (Fig. 39) occurs in which the interior of the 
labial palpus, including apex of second segment, the whole of head and thorax medially, are 
pastel yellow ; and the fore wing is more heavily suffused with dark brown or fuscous, excepting 
along dorsal margin which is whitish, sometimes with an admixture of yellow, and in most 
examples with a short outward-oblique linear dash projecting from before middle; the dorsal 
streak terminating in a small similarly coloured blotch at tornus; a similar slightly smaller blotch 
obliquely above on costa at about f .

A distinctive species by virtue of the wing pattern which differs from that of other known 
species of Elachista, and the only representative of this genus recorded from the alpine region 
of Ruwenzori. 

SCYTHRIDAE 

Scythris philorites sp.n. (Figures 40, 157-159) 

o* 10-13 mm. Labial palpus pale yellow, apical half of second segment and whole of terminal 
segment except base overlaid with fuscous exteriorly. Head, thorax and tegula bronze, head 
shiny, tip of tegula and medial area of thorax tinged purplish. Antenna fuscous-black. Fore wing 
fuscous-black, moderately sprinkled with whitish scales along costal margin and in apical area; 
a broad white streak from base along plical fold to tornus, slightly constricted at middle and 
dilate near tornus ; cilia dark grey, those below apex to near middle of termen pale yellow apically. 
Hind wing dark grey, cilia concolorous. At the base of the abdomen a pair of hair-pencils arise 
dorso-laterally on the first somite, as shown in Fig. 159. "When not expanded these are concealed 
in longitudinal pockets or folds in the first and second pleurites.

A distinctive species, tentatively assigned to the composite genus Scythris and placed near S. 
aphanatma Meyrick which it resembles in size and general coloration. The two species may be 
separated by the absence of the white plical streak on the fore wing in aphanatma, and by the 
coloration of the head which is light yellow in aphanatwa, compared with bronze in philorites. 

ARGYRESTHIIDAE 

Argyresthia lamiella sp.n. (Figures 41, 42, 160-166) 
6* $ 11-12 mm. Labial palpus greyish, apical halves of second and terminal segments suffused 
fuscous. Head whitish grey, roughened scales on crown and vertex light greyish ochrcous or dull 
ochraceous. Antenna whitish grey, flagellum with somewhat diffuse greyish fuscous annuli. 



108 Ritwenzori Expedition, 1952. Volume II, Number 12 

Thorax and tegula somewhat shining pale golden or coppery golden; thorax broadly suffused 
with whitish grey or grey medio-dorsally. Fore wing coloration and markings variable, male 
usually with markings more obscure than in female; ground coloration in male white suffused 
with a mixture of pale golden and fuscous, a series of compacted striae along costa from about ^; 
several diffuse ill-defined whitish patches along inner margin (dorsum), a sprinkling of whitish 
scales in apical area; female with ground colour whitish, a semblance of three golden-brown 
fasciae, first strong on inner margin at about \ forming a quadrate blotch, obsolete at middle of 
wing, reappearing on costa; second at about middle of inner margin, similar and parallel with 
first; third terminal, very narrow, not always discernible; costa basad of first fascia usually pale 
grey, a sprinkling of whitish scales around apex and along termen; cilia pale grey v/ith a weak 
golden tinge. Hind wing pale grey; cilia matching, with a weak golden tinge.

In general appearance this species is reminiscent of the European A. goedartella (Linnaeus), but 
the two are not likely to be confused since they are allopatric. The only other Argyresthiid 
belonging to this genus known from E. Africa is A. liparodes Meyrick, which is readily recogniz- 
able from lamiella by the whitish head and labial palpus, and the whiter general appearance of the 
fore wing which lacks the golden-brown fasciae of lamiella. 

ETHMIIDAE 

Ethmia phricotypa sp.n. (Figures 43, 167, 168) 

o* 24 mm. Labial palpus black, second segment lightly sprinkled with whitish scales exteriorly 
and below, narrowly ringed with white apically; terminal segment with white submedian and 
apical annuli. Head with face purplish black, crown white. Antenna purplish black, scape white 
below. Thorax and tegula white, a purplish black quadrate blotch at base of tegula, a similar 
marking medially on prothorax, a third smaller marking on metathorax. Fore wing purplish 
black except on inner margin along which extends a narrow white streak the inner edge of which 
makes strong incursions into the black area as follows : near base, at J, this closely followed by a 
slight indentation, and before tornus; a large white post-tornal blotch extends into cilia up to 
middle of termen; cilia beyond this point purplish black, somewhat brownish around apex; 
costal margin of wing sparsely sprinkled with sordid white. Hind wing butter yellow basally, 
becoming greyish distally; a pecten of long greyish yellow hair-like scales arises on basal half of 
subcostal vein. Fore and middle legs black; tibia of middle leg ringed with white at middle, and 
bearing small white external spots at base and apex; tibia of fore leg similarly but less strongly 
marked, whitish annuli at base and apex of first (basal) tarsal segment; hind leg deep butter yellow 
becoming blackish towards apex of first tarsal segment, tarsal segments marked with white apical 
bars dorsally.

the costal half of the fore wing and by the yellowish coloration of the hind wing. 

COLEOPHORIDAE 

Coleophora tacera sp.n. (Figures 44, 169-171) 

S § 1 1-1 5 mm. Labial palpus with terminal segment slightly larger than second ; projecting apical 
tuft on second weakly developed, very short; sepia, in male usually wholly overlaid with light

Metriochroa celidota sp.n. (Figures 45, 172-175) 

o* $ 7-9 mm. Labial palpus sordid white, suffused with greyish or blackish fuscous, usually more 
strongly exteriorly. Head greyish with a strong gloss, crown darker posteriorly. Thorax and 
tegula greyish or fuscous mixed with greyish. Antenna and scape dark greyish fuscous; apical 
fifth of antenna whitish. Fore wing blackish fuscous, somewhat lightened by an admixture of 
greyish basad of postmedial fascia; two silvery- white transverse fasciae, first at about J poorly 
defined and partly obliterated, especially towards inner margin (dorsum) by a suffusion of greyish 
fuscous; second fascia at about f, comparatively bold and well-defined, free from extraneous 
suffusion, extending a little into cilia at tornus, inner edge almost straight and slightly inward- 
oblique from costa, outer edge shallowly concave; an obscure partial fascia or transverse elongate 
diffuse white patch near costa a little before middle, absent in female; cilia dark grey, paler around 
termen and inner margin. Hind wing and cilia grey. Legs wholly grey, depth of colour varying 
between specimens.

Near M. argyrocelis Vari, described from S. Rhodesia, but at once distinguished superficially 
by difference in arrangement of the white markings of the fore wing, argyrocelis having small 
broken markings on the costa and tornus in place of the complete transverse postmedial fascia 
in celidota. 

Caloptilia pachyspila sp.n. (Figures 46-48, 176-180) 

o* 9-12 mm. Labial palpus dark grey. Head varying from wholly whitish to dark grey, frons often 
paler than crown. Thorax and tegula dark grey. Antenna dark grey, a broad whitish subapical band. 
Fore wing pattern variable, type (Fig. 46) and one paratype as follows : ground colour fuscous- 
black diffusedly mixed with greyish, marked with three white fasciae, the first sub-basal, very 
diffuse and comparatively inconspicuous ; second a little before middle, comparatively bold and 
broad, directly transverse and with well-defined margins; third at about f, outer edge directly 
transverse, inner edge slightly incurved from costa; a weak bronzy sheen covers the whole wing 
and is also faintly discernible on the thorax and crown of head; of the remaining paratypes, five 
have generally lighter ground coloration than the type, the coloration of the head is also lighter 
(whitish), but the fore wing lacks the bold white fasciae, these being represented by small white 
markings, varying in size and number, along the costal and dorsal margins and in the apical 
area, as shown in Fig. 47; in these paratypes the bronzy sheen is evident; in two paratypes from 
Mt. Stanley (Fig. 48) and Balirungi R. the fore wing is a uniform fuscous-black diffusedly mixed 
with greyish, the white markings being entirely absent, and in only the Balirungi R. specimen is 
there a trace of the bronzy sheen. Hind wing and cilia grey. 

Male genitalia (Figs. 176-180). In the holotype, Fig. 176, the prong projecting from the ventral 
margin of the valva a little basad of the apical flange is vestigial but in some examples examined 
was found to be more strongly developed as shown in Fig. 178. In Fig. 180 are shown the expans- 
ible hair-tufts arising laterally on the Vllth somite.

The remarkably wide variation in the superficial appearance of pachyspila does not appear 
from the material examined to be related to locality or elevation. The sombre general coloration 
and, when present, the white markings of the fore wing, distinguish this species from the 
species which follows, C.janeae Bradley, next which it is tentatively placed. 

Caloptilia janeae sp.n. (Figures 49, 50, 1 81-186) 

cT 9 16-21 mm. Labial palpus blackish sepia, apex of terminal segment, base and underside of 
second segment overlaid with pale sulphur yellow. Head blackish sepia, mixed with pale sulphur 
yellow laterally. Antenna dark grey. Thorax and tegula blackish sepia, thorax with a longitudinal 
sulphur yellow lateral streak, tegula tipped with pale sulphur yellow. Fore wing sulphur yellow, 
markings variable, consisting mostly of small, irregular, scattered blackish sepia dots and patches, 
sometimes confluent medially; cilia brownish grey from apex to inner margin, an admixture of 
dark sepia along termen, sometimes a sprinkling of sulphur yellow at base along termen; indian 
yellow above apex. Hind wing grey, cilia brownish grey. 

Two of the paratypes, a male and female from the type locality, represent a form in which the 
sulphur yellow coloration of the fore wing is replaced with light brown, the male having the 
dark markings greatly reduced and less intense than in the typical form, the female lacking these 
markings altogether and having the fore wing an almost uniform dark brown.

The sulphur yellow coloration and the intricate pattern of broken blackish sepia markings of 
the fore wing in the typical form distinguish this species from C. pachyspila and other members 
of the genus. 



PHYLLOCNISTIDAE 

Phyllocnistis loxosticha sp.n. (Figures 51, 187-190) 
6* 9 7 mm. Labial palpus, head, thorax and tegula white, a trace of yellowish sheen on palpus and 
head; thorax broadly suffused with dark olive brown medially; tegula narrowly edged with 
dark olive brown along outer margin. Antenna white; a longitudinal olive brown dorsal line 
from base of scape to apex of flagellum. Fore wing white, a weak yellowish sheen sometimes 
evident; two thick parallel median longitudinal dark olive brown lines from base, upper (costad) 
reaching to middle, lower to §, enclosed space greyish pale yellow; a dark olive brown line from 
costa at I, outward-oblique from costa to middle thence inward-oblique to inner margin (dor- 
sum), followed by two similar streaks from costa, originating in cilia, and preceded by a similar 
but stronger and well-defined very oblique line from middle of costa, terminating at end of lower 
ohve brown medial line, all these lines from costa inwardly edged with a broad suffusion of pale

Allied to the palaearctic P. saligtia Zeller, but differing superficially in the very much more 
oblique linear marking from the middle of costa, and in the elongate black apical dash which in 
saligna is in the form of a round dot. 



EPERME NIID AE 

Epermenia oriplanta sp.n. (Figures 52, 53, 191-195) 

o* $ 13-27 mm. Both sexes variable in size and appearance; in the type series the majority measure 
about 22-24 mm., the largest in the series being the holotype male, and the smallest a paratype 
male with the same data. Labial palpus warm buff or ochraceous-buff, infuscate exteriorly; 
terminal segment and apical part of second segment sometimes overlaid with fuscous-black. 
Head warm buff or ochraceous-buff, variably suffused greyish, fuscous or fuscous-black; frons 
sometimes with whitish admixture. Thorax and tegula warm buff or ochraceous-buff mixed or 
wholly overlaid with greyish, fuscous or fuscous-black; frons sometimes with whitish admixture. 
Thorax and tegula warm buff or ochraceous-buff mixed or wholly overlaid with greyish, fuscous 
or fuscous-black; tegula frequently tipped with white scales. Antenna in female minutely ciliate 
along anterior margin to near base, basal segments, dorsal and posterior surfaces of flagellum clad 
with greyish fuscous or fuscous scales, usually darker towards apex of antemia, usually a trace of 
ochraceous admixture in basal segments, individual segments often lighter proximally, scape 
fuscous-black dorsally with a trace of ochraceous admixture, underside of scape and basal segments 
of flagellum whitish cream; antennal flagellum in male wholly ciliate, ciliations about \ width 
of shaft, shaft thickened beyond base, gradually tapering apically, scape and basal segments clad 
with fuscous scales with variable ochraceous admixture, remainder of segments except near apex 
each spotted posteriorly with a small scallop-like tuft of whitish scales. Fore wing ground colour 
white, overlaid with variable fuscous-black irroration, a variable admixture of ochraceous-tawny, 
in some examples this is very strong and forms diffuse patches especially in middle and discal 
areas of wing ; inner margin (dorsum) bordered with white to beyond middle, a raised blackish 
scale-tooth at about J, a smaller tuft beyond middle at end of white border; sometimes a few 
white scales partly encircling a black discal dot at end of cell, less frequently a sprinkling of white 
scales extending into cell area; cilia light buff, a blackish medial line along termen, cilia apicad 
of tornus to near middle of termen suffused fuscous. In allotype female and four paratype males 
the ochraceous-tawny coloration is obliterated by heavy fuscous and fuscous-black suffusion; in

This species is apparently a close relative of E. epirrhicna Meyrick, described from the Pare 
National Albert from one specimen, which I have not seen. E. oriptanta differs superficially from 
epirrhicna which, according to the original description, does not have ochraceous-tawny coloration 
in the fore wing and has a basal patch of dark fuscous suffusion, and has the thorax white mixed 
with grey.

A truly montane species of Plutellid having greatly developed wing expanse and occurring 
mainly at higher elevations in the ericaceous zone and extending into the alpine belt. The fresh 
material shows evidence of considerable superficial variation within the species. In the typical 
form the dorsal markings of the fore wing are well-defined and the inner and terminal margins 
are mixed with whitish; in some examples the margins are diffuse to varying degrees and may 
sometimes be mixed with ochreous. 

P. orosoma appears to be a near relative of the Abyssinian species P. oxylopha Meyrick and the 
European species P. iucariwtella Steudal, but most remarkable is that it seems to be more nearly 
related to P. culminate Meyrick, which occurs in South America. A comparison of the genitalia 
of the type female of culminata, which is in the British Museum, with those of orosoma shows 
them to be structurally very similar.

This species has previously been known only from the type, a male collected at Bujuku at 
12,000 ft. The additional material, in excellent condition, is therefore of particular interest. It 
shows that hyacinthopa is remarkably widespread on Ruwenzori and occurs in the various floral 
zones from 4,500 to 14,500 ft. It shows also that the species is variable superficially. The wing 
expanse of the fresh material ranges from 19 mm. to 25 mm., compared with that of the type 
which measures 22 mm. Besides representing the norm in wing expanse the type specimen is 
remarkable in that it is also intermediate in the extent of white scaling in the distal area of the 
fore wing. In some of the additional specimens the white scaling is greatly reduced, while in 
others it is heavier and more extensive than in the type.

This species has previously been known only from the type material : two males, not a male 
and female as stated by Meyrick in the original description, collected on Ruwenzori at 10,000 ft. 
The additional material reveals that considerable variation occurs in the coloration and fore 
wing markings in this species. In the typical (type) form the dark markings of the fore wing 
are strongly defined and contrast with the pale yellowish ground colour. Among the fresh 
material, six of the seven specimens from Bigo, 11,400 ft., are of the typical form, having the 
fore wing markings strong and well-defined, while the seventh specimen from tins locality has 
the fore wing strongly suffused with fuscous obliterating the pattern and making the wing an 
almost unicolorous brown in appearance. None of the specimens from other localities match 
the types exactly, and have the wing pattern variable and often reduced or partially obscured by 
fuscous suffusion.

Evans & Fletcher (1958 : v) comment on this species: "... found in numbers on the trunks 
of the Senccios, among the accumulated dead foliage, on which the larvae almost certainly feed". 

Closely related to T. luridula Meyrick, an alpine species from Abyssinia. The unique type of 
luriduh is in the British Museum and on re-examination during the present study was found 
to be a male and not female as stated by Meyrick in the original description. In general appear- 
ance it closely resembles allomella though somewhat paler in coloration; it differs most noticeably 
in having the head yellowish (pale ochraceous-orange) and in lacking the blackish stigma 
present on the fore wing in allomella.

considerable interest. It has been pronounced as certainly new by Mr. A. G. Carolsfeld-Krause 



Microlepidoptera

of Copenhagen, Denmark, to whom I am indebted for guidance in compiling the foregoing 
description, notably of the genitalia characters, and for comments on the generic position of the 
species. 

S. ruwenzoriensis is closely related to the group of species from South Africa described in the 
genus Stigtnella by Vari (1955, Ann. Transvaal Mus., 22 : 331-336). It can be placed near S. 
oleivora Vari, from which it may be distinguished by the long and very narrow fore wing, and 
by the absence of markings on the fore wing except for the moderately prominent tornal spot. 
S. ruwenzoriensis is not typical of the genus Stigmella, and the present generic position should be 
regarded as provisional, having been adopted as a matter of expediency because the nearest 
apparent relatives have been assigned to that genus. The structure of the male genitalia shows 
certain characteristics of the palaearctic genus Fomoria Beirne, and it is likely that the generic 
afhnities of ruwenzoriensis and its congeners will prove to lie with that group. Certainly they 
belong in the dechtirioid section of the Nepticulidae with large hood-shaped tegumen.
